The Blind Person's Allowance is an extra amount of income that blind people can earn without having to pay tax on it. It is added to your tax-free personal allowance.
Blind Person's Allowance is paid to people in England and Wales who are registered as blind/severely sight impaired (SSI) with a local authority.
It is paid to people in Scotland and Northern Ireland who:
have been certified as blind by an eye specialist,
or, have not been certified but are so blind that they cannot do any work for which eyesight is essential.
The allowance is the same for everyone who is entitled to it, regardless of age or income.
Blind Person's Allowance
Blind Person's Allowance for 2015-2016 is £2,290
So if, for example, you're 58, registered blind with your local authority and have:
an annual salary of £15,000
a Personal Allowance of £10,600
Blind Person's Allowance of £2,290
you only need to pay tax on £2,110 (£15,000 less the sum of £10,600 and £2,290).
Spouse or civil partner's unused allowance
If you have a spouse or civil partner who can claim the allowance but doesn't use it in full (because their total taxable income is less than their total tax-free allowances) you can add any unused amount to your allowance. The calculator can not take into account any unused amount that you are allowed to add to your personal allowance.
If your tax bill isn't high enough to use up all of your Blind Person's Allowance you can use form 575 'Notice of transfer of surplus Income Tax allowances' to transfer any unused allowance to your spouse or civil partner.
If you don't pay tax and your spouse or civil partner does you can still transfer your unused allowance to them.
If you are able to claim Married Couple's Allowance you must transfer any unused allowance when you are transferring your unused Blind Person's Allowance.
If you are not already receiving your spouse or civil partner's allowance you may need to ask your tax office to transfer it to you.
